Aerospace aluminum is an ultra-high-strength deformed aluminum alloy that is currently widely used in the aerospace industry. It has good mechanical and processing properties, good plasticity after solution treatment, good heat treatment strengthening effect, generally high strength below 150 ° C (or even higher), good toughness, is an ideal structural material.

Compared with ordinary aluminum alloys, aluminum alloys for aircraft have higher requirements on strength, hardness, toughness, fatigue resistance and plasticity. Due to the light weight and light weight effect of aviation aluminum, it has replaced steel and occupied the dominant position of current aviation materials. Aviation equipment has higher requirements for aluminum and is an important high-end application market for aluminum.

There are many kinds of aluminum alloys used on airplanes. The aluminum alloys used in aviation aircraft structures in the world today are mainly high-strength 2 series (2024, 2017, 2A12, etc.) and ultra-high-strength 7 series (7075, 7475, 7050, 7A04, etc.), and some 5 series (5A06) , 5052, 5086, etc.) and 6 series (6061, 6082, etc.) and a small amount of other series of aluminum.

2, super hard aluminum: aluminum zinc magnesium copper alloy. Commonly used 7075, 7A09, high strength limit and high yield strength, with a large load, used to make the upper wing skin and girders on the wing.

3, anti-rust aluminum alloy: commonly used aluminum-magnesium alloy 5A02, 5A06, 5B05. It has high corrosion resistance, fatigue resistance, good plasticity and weldability. Used to make mailboxes, tubing, etc.
